You are trying to Delete the record from a Table which has a reference in another Table. Here REFERENCE constraint is  FK_ASM_MASTER_DEPOT_MASTER1 . In Database FEDERAL_CNN there are tables ASM_MASTER. DEPOT_MASTER1 and ASM_MASTER . DepotCode column is referenced by DEPOT_MASTER1 Table. So you need to delete from DEPOT_MASTER1 Table first and then delete from Table ASM_MASTER . If you want to delete a row then you have to execute the following two queries in sequence. DELETE FROM DEPOT_MASTER1 WHERE UserId = [UserIdToDelete]; DELETE FROM ASM_MASTER WHERE UserId = [UserIdToDelete];
